# Shift planning routes (employee)

Mounted at `/api/shifts`. Every route requires `requireAuth` +
`requireEmployee`.

# Examples

```
GET /api/shifts/available?period=YYYY-MM
200 -> { "slots": AvailableSlot[] }
```
Open slots the employee isn't already signed up for. `period` defaults to
the current month if omitted/invalid. Also the trigger point for lazily
generating that month's template — see
[shift_slots](/docs/data-model/shift-slots.md).

```
GET /api/shifts/mine?period=YYYY-MM
200 -> { "slots": MySlot[] }
```

```
POST /api/shifts/:slotId/signup
201 -> { "ok": true }
400 -> collision with another approved slot, already full, already signed
       up, or the slot is closed — see [shift_signups](/docs/data-model/shift-signups.md)
```

```
DELETE /api/shifts/:slotId/signup
204 on success
400 -> not signed up for that slot
```
