Months
Statute of limitations

T
Threaten
Job loss, plant closing, reduced benefits if union wins
I
Interrogate
Ask employees about union activity or sympathies
P
Promise
Promise raises or benefits to discourage organizing
S
Spy/Surveil
Surveil meetings, social media, organizing activity
other section 8(a) violations

- › 8(a)(3) — Discriminate against employees for union activity
- › 8(a)(4) — Discriminate against employees for filing charges or testifying
- › 8(a)(5) — Refuse to bargain in good faith with certified union
Section 8(b) — Union ULPs
Both sides have ULP exposure. The union side is less famous but tested.
Restrain or coerce employees in Section 7 rights
Cause employer to discriminate against an employee
Refuse to bargain in good faith
Engage in secondary boycotts
Picket for recognition without filing for election
Exam Traps
TIPS is for EMPLOYERS during organizing
Threaten, Interrogate, Promise, Spy. Each one alone violates Section 8(a)(1). Most-tested mnemonic.
6-month statute is strict
Charges filed after 6 months are dismissed regardless of merit. Settlement negotiations do NOT pause the clock.
Replacing economic strikers vs ULP strikers differs
Economic strikers can be permanently replaced. ULP strikers can only be temporarily replaced and must be reinstated upon offer to return.
Union ULPs exist too
Section 8(b) covers union violations like causing employer to discriminate, secondary boycotts, and recognitional picketing without filing.
TIPS at the campaign
Threaten Interrogate Promise Spy. Four employer ULPs during organizing. Each alone violates Section 8(a)(1).
6 months, no pause
ULP filing window does not pause for negotiations or settlements. Late filing = dismissed.
Boss cannot threaten layoffs if they vote yes (Threaten).
Interrogate. Even private one-on-one is interrogation in this context.
Promise. Conditional benefit dangling.
Spy. Surveillance of organizing activity is always a ULP.
Section 8(b) catches the union side — coercion of employees, secondary boycotts, illegal picketing.
