As someone who's been party to several employment transfers/mergers:
1/ I'd be really distrustful of new owners who walk in and start hacking and slashing. Most want to get the lay of the land, see how the customer base is faring, take time developing an action plan. Can take anywhere up to two years. But when the changes come, they can be significant, but they'd better have come with diligent planning.
2/ We always tend to overestimate how many people are at "Head Office." Might be three guys in an apartment full of pizza boxes, for all I know.
