Family reasons is just an excuse to resign when the going gets tough.
I asked Google AI which companies are living to JB, below is appended the answer.
Koh Poh Khoon is a coat tail MP and came in easily in good times (i.e. on a coat tail) when economy was doing well and citizens had good jobs.
Now, rent and business costs are high and companies are withdrawing for lower cost locations to operate abroad, just as Trump anti globalisation is not retreating. This obviously means a much higher workload for the minister of manpower to correct structural manpower issues- sacred cows and elephants in the room which needs to be handled as citizen favourite jobs migrate and difficult jobs with low pay and prejudiced by societal bias and ostracism cannot find any cizen employees except the foolish and reckless (e.g. PAP never upgraded rank and file construction jobs nor significantly improved their safety, so they are taken by foreigners and locals go jobless as their favourite employers pull out of Singapore due to high business costs issues).
That's why more and more PAP ministers of state, aka middle management, will resign because they were never real politicial leaders to begin with.
They never grew up from grassroots and cannot find the reason to fight hard for the country.
The GRC system is also unnatural and based on the Patronage system whereby cabinet is like a mafia organisation hq totally opaque and secretive in its deal making, so it's difficult for good, honest people to get close.
Probably Lawrence Wong is planning a cabinet reshuffle or Ng Chee Meng needs a position so a letter was circulated for those who wanted to resign from cabinet to do so early so a good PR campaign could be orchestrated without citizens getting surprised or alarmed.
It is also probably LW/PAP Exco telling all PAP MP that bottom line is they cannot resign as MP or face wrath of entire PAP party because it is known that one main purpose of GRC system is to abolish the inconvenience and accountability of a by-election which under GRC rules, will not happen under GRC system because of the high degree of secrecy and opacity the PAP is run on. By-elections are the nemesis of PAP which relies on dirty tricks like sudden declarations of snap elections, last minute election boundary declarations after massively gerrymandering the boundaries to set up a PAP victory, absurdly short campaign periods allowing such minimal depth of political debate that the issues usually revolve around blank promises and pork barrell politics which PAP inevitably wins because only they know what reserves are available as sweets. Massive grandstanding prevails and the elections are always called long before any political debate matures with a scaremongering PM always having the last word that times are dangerous and the incumbent is the only safe choice. By elections are totally different because usually, the PAP cannot delay them indefinitely and the election boundaries cannot be changed so all registered political parties can immediately begin discussing political issues from the day a qualifying parliamentary seat is vacated. PAP is extremely fearful of this situation to the extent that they invented the GRC system with it's subsequent going undemocratically overboard, abusing political authority by nearly doubling GRC sizes in parliament in massive political overreach and significantly diluting minority representation per GRC instead (1988: 13 GRC occupying 39 of 81 parliamentary seats, 3MP/GRC, 42/81 opportunity of by elections; 1997-2006 era, 14-15GRC of 5-6MP/ GRC, 9/84 opportunity for by-elections).
Opaque mafia operating in Patronage systems work this way, otherwise, there is no reason to invent the GRC system to effectively abolish the by-election system in the ~ 90% of parliamentary constituencies the illogical system now operates.
In a system run by the mafia, smoke and mirrors is always the standard operating procedure, by default, always....

Numerous Singapore-based and multinational companies are moving or expanding their manufacturing and logistics operations to Johor Bahru (JB) to cut costs and capitalize on the Johor-Singapore SEZ. Recent high-profile examples include:
Gardenia Foods: Shifted its large-scale bread and bakery production from Singapore to JB.
Asia Pacific Breweries (Tiger Beer): Phased down large-scale brewing operations in Singapore to consolidate production in Malaysia and Vietnam.
Yeo Hiap Seng (Yeo's): Relocated local can-making roles and consolidated canning operations in Malaysia.
Archisen: An agritech firm that committed to developing a 200-acre smart indoor agricultural hub in Sedenak, Johor.
Agrocorp International: Built a plant-based food and dairy-free cheese processing facility in Johor.
Emplifi: A Singapore-based HR firm that launched co-working spaces in JB to assist other SG businesses in establishing operations there.
Sin Chew Woodpaq: A logistics and packing provider that set up a cross-border facility in Seri Alam, Johor, to support clients moving across the Causeway.
Companies typically keep their corporate headquarters, research and development, and quality governance in Singapore, while using JB's lower operating costs and incentives for large-scale production
