I have a Cannondale Synapse 2, just bought it near the end of last season and I had a tune up done two weeks ago. A coworker noticed the rear wheel wobbles side to side.
What’s the issue/fix?

Take the wheel off, snug down the cones/preload on your rear wheel bearing just until you feel a bit of grinding when turning with your fingers, then back off 1/8-1/4 turn. Lock the cones down with the lockring so they don’t come loose again.
This is the tuneup guys’ fault. If adjusting bearings was not included in the work, at the very least they should have offered to do it for a small additional price. If it was, this should be fixed as warranty.
Wheels should have absolutely zero sideways movement like this. It’s pretty bad.
Bearing in hub needs to be checked. If you can, as long as you have it off the bike check bearings and races and lube.
As other commenters said, it’s likely the cones not being tightened enough. Theres a sweet spot between loose and wobbly and too tight so that it is actively putting resistance on the axle and bearings.
Alternate possibility is a cracked/broken axle, but I think the side to side play usually tends to be a bit wider. Still worth checking since you will need to get to the cones anyway
