I suppose it depends on how the mail client handles the case of multiple valid
UIDs on different keys matching the e-mail address. The GnuPG command line
simply picks the first in the keyring. If the mail client also does this, it's
entirely unpredictable which one will be picked by others. In this case, it
would be ideal if the mail client prompted with the two matches, allowing the
sender to pick one. Although it's debatable whether it should do this every
time; it might become annoying.

Maybe someone else knows more...

But keeping the e-mail address of your old employer with the scheme I proposed,
just means that your new employer will in principle have access to messages
encrypted to the work key. This might not be objectionable when you have left
your previous employer. It depends on the scenario; what type of mails people
send you after you have left the first employer.

If you have the private keys of the work key at home, you will also have access
to the mails sent to the work key. But I suppose you meant: at home but /not/ at
my new job.

HTH,
