I'm due back at work in a month having taken a year's maternity leave, but I'm starting to get a little concerned. I've emailed my line manager twice over the past fortnight about my return to work and haven't had a reply from him. I know I could be paranoid, but it's out of character for him. On top of that, there have been big structural changes at work since I've been away including a few departures (I haven't been formally told this, I've just heard it on the grapevine) so I'm bracing myself for an unpleasant surprise.
What I'd love to know at this stage is how I should be handling myself. Do I start copying HR into my emails? Should I phone my line manager (I've avoided this because I like to keep things documented)? On top of everything else, it's a real incovenience not to hear anything because I need my line manager to agree to my holiday request (I've accrued the year's holiday time, so I've proposed phasing the holidays over 6 months, effectively making me part time. However I need his agreement before I can finalise childcare).
Any other advice would really be appreciated.
